It is clear to me that antisquad is acceptable when reach around 50%, but what happend when upper links, on 3 or 4 links setup, has a higher angle than lower links and their proyection never match? If not, neither will intercept force vector.

I assume that is a infinite antisquad. Is that right?

Sorry if grammar is failing.

If the links ara parallel then the line of action is from the tyre contact point and parallel with the links (just assume that the links are very slightly convergent so that they converge at a distance a very long way away) You will still have antisquat cause the links will run upwards on an angle.

If the links diverge then the intersect will be behind the axle. The diagram will still work. Draw from the intersect through the tyre contact point. If the line points downwards then as the rig is throttled the rear will pull downwards (this is when the links are steeply divergent and the convergent point is behing the rear axle but above the ground) If the links arnt so steeply divergent then the convergence point is behind the axle and below the ground which gets back tothe normal antisquat arrangement.

Think of it this way - a link setup that is parallel and doesent converge gives a certain amount of antisquat. If they are very slightly convergent you will get the same antisquat (convergent point long way in front at the angle of the links) and if they are very slightly divergent (convergent point long way behind the axle at the angle of the links - as in way below ground level) you will still get about the same level of antisquat.

Sorry to have rambled but Ive only just thought about this now and of course this is all just my opinion.

Is the affection on links of different leght only in pinion angle when going upgwards and downwards on does they have other implication?
